Title: Production of magnetic disk
Inventor: KUMAGAI MUNEHITO
IPC: G11B5/84
Filed: 1988-04-11
Abstract: PURPOSE:To obtain good reproduced output by subjecting a protective film to pattern etching, thereby forming the film to a desired shape and surface roughness. CONSTITUTION:A magnetic film 2 is deposited by plating, sputtering, etc., on a substrate 1 and after the protective film 3 is formed thereon, the film 3 is etched by using a mask material 5 and is thereby formed to the arbitrary rugged shape. Finally, a lubricating agent 4 is deposited on the protective film to improve the slip between the magnetic disk and a head, by which the magnetic disk is obtd. Since the ruggedness on the magnetic disk surface can be formed only to the film 3, the protective film can be formed to the arbitrary shapes, distributions, pitches, and sizes of the ruggedness. Not only the uniform ruggedness is thereby obtd. with good reproducibility but also the fluctuation in the reproduced output by a spacing loss is eliminated as well.

Abstract: PURPOSE:To detect a direction, too of a cylindrical body having no seam bulge without generating an ignition in case of handling an ignitable substance, and without damaging the periphery of the cylindrical body, by detecting a magneto resistance variation by the cylindrical body rotated by a magnetic detecting sensor. CONSTITUTION:A magnetic flux from a magnetism sending coil of a magnetic sensor 4 is sent out to a metallic round can 1 rotated on a conveyor by a supporting roller 2 and a rotary roller 3, and the magnetic flux returned from the can 1 induces a voltage in a magnetism receiving coil.

Title: Liquid crystal display device and its production
Inventor: MIYOSHI KOZO
IPC: G02F1/1368
Filed: 1995-04-14
Abstract: PURPOSE: To suppress the occurrence of a disconnection of upper layer wirings by adopting the constitution in which the sectional shape of lower layer wirings or the sectional shapes of the lower layer wirings and insulatable films have a difference in level. CONSTITUTION: This liquid crystal display device has the lower layer wirings 2, the insulatable films 3 formed on the surfaces of the lower layer wirings 2 and the upper layer wirings 4 formed on the insulatable films 3. The sectional shape of the lower layer wirings 2 or the sectional shapes of the lower layer wirings 2 and the insulatable films 3 have the difference in level. The ground surfaces for forming the upper layer wirings 4 are all the insulatable films 3 formed by an anodic oxidation method near the active element regions. The size of the difference in level at which the upper layer wirings 4 overlap at one time is, therefore, reduced. The disturbance in the crystallinity of the upper layer wiring materials in the regions to be overlapped is consequently lessened.  The films forming the upper layer wirings 4 dot not produce a difference in the film quality near the active elements. Then, the upper layer wirings 4 are liable to be overlapped and further, the difference in the film quality near the active elements does not arise and, therefore, the pixel defects in the stepped parts by the disconnection are decreased.

Title: Semiconductor device
Inventor: YAMAUCHI MASAHIDE
IPC: H01L23/34
Filed: 1987-04-10
Abstract: PURPOSE:To prevent a crack in a ceramic substrate by fixing a metal stud on a metal base back through a ceramic plate of the same material with the ceramic substrate or having a near thermal expansion factor. CONSTITUTION:When electric power is supplied from outside through a lead and a thin wire to a semiconductor element 5, a part is taken outside as a signal and the rest is emitted from the semiconductor element 5 as heat. This heat is radiated to an external radiating body through a solder 6, a ceramic substrate 3, a wax material 4 and a base 1. Since at this time the base 1 is composed of a metal having good thermal conductivity such as copper, good thermal conductivity can be secured. As the ceramic substrate 3 and a ceramic plate 7 having equal thermal expansion factors are stuck to the surface side and the back side of the base 1, each member composing this device is hard to bend even when a semiconductor device is held at a low temperature and accordingly the stress to be generated to the semiconductor element 5 and the ceramic substrate 3 is reduced so that these are hard to break.
